RECORD-DIAL-SUPPORTING DEVICE FOR WATCHMENS TIME-RECORDERS.

Application filed September 23, 1910, Serial No. 583,331.

To all whom it may concern:

Be it known that 1, CHARLES H. JENKINS, a citizen of the United States, residing at- Belleville, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Record-Dial-Supporting Devices for \Vatchmens Time-Recorders, of which the following is a full, clear, and exact description.

This invention relates to watchmens timeregisters, more particularly of the type de scribed in the patent of A. A. Newman, No. 676,764, issued June 18th, 1901. In registers of this type the record sheet is in the form of a disk of paper, graduated circumferentially by radial divisions corresponding to predetermined time intervals. For example the disk or dial may be divided into twelve spaces or parts, constituting hour divisions, and each hour space may be divided into smaller divisions each corresponding to a certain number of minutes. This dial is operatively connected with the hour-arbor of a suitable clock in such manner that the two will rotate in unison, the dial thus making a complete rotation in twelve hours. The record dial or disk is also arranged with its time-graduations in register with those of the clock. Recording devices are provided, arranged in fixed positions relative to the rotating record dial and constructed to be operated by suitable keys to which the watchman has access. The recording devices include a marking device, for example a die or punch, adapted to make a die-mark or perforation or other mark, on the disk at each insertion and aetuation of a key. This mark will then indi cate at a glance the time at which the watchman used the register.

My present invention pertains to the means for mounting or securing the record dial or disk in the clock in operative connection with the proper time-driven arbor, preferably the hour arbor, and its chief object is to provide improved means for the purpose, enabling the disk to be easily and conven iently positioned and locked in register with the graduations on the clock face.

To this and other ends the invention consists in the novel features and combinations of elements hereinafter described, and more particularly set forth in the appended claims.

The preferred embodiment of the inven- Specifieation of Letters Patent.

tion is illustrated in the accompanying drawing, in which- Figure 1 is a plan view of the time-regis ter with the back of the casing removed to show the record disk in position but reversed to show its graduations. Fig. 2 is a central cross section of Fig. 1. Fig. 3 is a view simi lar to Fig. 1 but with the record disk removed. Fig. at is a plan view of the record disk, and Fig. 5 a bottom plan view of the clamping cap.

The circular plate 10, Fig. 2, is the member which supports the record disk 11, and is provided with a neck or tubular stem 12 encircling the hour-arbor 13 of the clock or some other suitable arbor rotating in unison therewith. The plate 10 and stem 12 are preferably permanently fixed to the arbor in any convenient manner, not shown. Projecting above the surface of the plate are three ribs 14f, extending radially from the stem or neck 12, the said ribs being spaced equiangularly apart in the present form and extending somewhat more than half the distance from the neck to the edge of the plate. The record disk is formed with a central circular aperture 15 to fit the stem or neck 12, and with radial slots 16 to fit closely the ribs, so that when the disk is placed in the clock the graduations on the disk will be in register with those on the clock-face and the former will be carried past the impression point (indicated by the die-plate 17 shown in dotted lines in Figs. 1 and 2) in proper order or sequence.

To fasten the disk on its supporting plate a removable cap 18 is provided, having a central aperture to fit the neck 12 and on its under face radial grooves 19 to fit the ribs 14. Around the upper part of the neck is a circumferential groove 20, and the cap is provided on its inside with one or more, preferably two, spring-actuating pins 21 having their ends rounded to fit the rounded surface of the said groove and so positioned that when the cap is pressed down on the neck the pins will snap int-o the groove and so hold the cap securely in place, pressing the record disk snugly against the supporting plate 10. To remove the cap it is only necessary to exert a slight pull on it with the fingers, thereby cannning the locking pins out of the groove. To replace the cap it is slipped over the stem and turned one way or the other until the ribs are felt in the grooves. The cap can then be pressed down into place.

From the foregoing it will be seen that the construct-ion described is simple, and con- 5 venient to operate, yet withal thoroughly effective. It is the preferred form of the invention, but it is to be understood that the invention is capable of other embodiments without departing from its proper spirit and scope as defined by the appended claims.

I claim:

1. In a watehmans time-register, in combination, a clock-driven arbor, a record-dial supporting plate encircling the arbor and rotating therewith, an extension on said supporting plate having a circumferential groove therein, said plate being provided with one or more radially'extending ribs to engage a correspondingly shaped slot or slots in a centrally apertured record-dial, a removable cap for holding the dial in position, and means engaging said groove for locking the cap in place.

2. In a watchmans time-register, in combination, a clock-driven arbor, a record-dial supporting plate encircling the arbor and rotating therewith, said plate being provided with one or more radial extending ribs to engage a correspondingly shaped slot or slots in a centrally apertured record-dial, a removable cap having in its under surface one or more radially extending grooves to fit the rib or ribs on the plate and having a central aperture to permit the cap to be slipped over the said arbor, and means for locking the cap in place.

3. In a watchmans time-register, in combin ation, a record-dial supporting plate having a stem and having one or more radially extending ribs to engage a correspondingly shaped slot or slots in a centrally apertured record-dial, said stem being provided with a circumferential groove, a removable cap having an aperture to fit said stem, and having one or more radial grooves to fit the ribs on said plate, and one or more springactuated locking pins carried by the cap and adapted to engage the groove in the stem whereby to hold the cap rcmovably en the stem.

4;. In a Watchmans time-register, in one bination, a record-dial supporting plate having a stem and having a plurality of ribs extending radially from said stem and spaced equiangularly apart, said stem being provided with a circumferential groove, a cap having an aperture to fit said stem, and having in its under surface a plurality of grooves to fit the ribs on said plate, and a plurality of spring-pressed locking pins carried by the cap and adapted to engage the groove in said stem whereby to hold the cap removably on the stem.

5. In a watchmans time-register, in combination, a clock-driven arbor, a record-dial supporting plate encircling the arbor and rotating therewith, said plate being provided with one or more extending ribs to engage a correspondingly shaped slot or slots in an apertured record-dial, and a removable cap having in its under surface one or more corresponding grooves to lit the rib or ribs on the plate and having a central aperture to permit the cap to be slipped over the said arbor.

In testimony whereof I athx my signature in the presence of two subscribing witnesses.
